Affinities. 



1. With A. doratoxylon A. Cunn. This is the species 

 with which A. Shirleyi has long been confused. 



A. doratoxylon is a tall shrub or small tree with range 

 from the Lachlan River, N.S.W., to Southern Queensland. 

 I am of opinion that Bentham had mixed material when 

 (at B.F1., ii, 403) he described A. doratoxylon; e.g., I doubt 

 his Northern Australian specimen (as indeed he does him- 

 self), and his Upper Maranoa, Q. (Mitchell) specimen might 

 be re-examined. 



A. Shirleyi attains a size far greater than A. doratoxylon 

 attains. It is more glaucous than A. doratoxylon, the 

 spikes are much longer and the flowers more interrupted, 

 the calyx more shallow, the corolla densely hairy and the 

 petals longer, the ovary densely hairy, the pods broader, 

 flatter, more moniliform and more woody, the seeds broader 

 and smaller, being only about half the length of those of 

 A. doratoxylon. 



2. With A. proxima Maiden. The chief points of differ- 

 ence are as follows. Phyllodes more falcate, gland raised, 

 not depressed circular as in A. proxima, and usually more 

 distant from the base. Spikes borne on a very short com- 

 mon peduncle (which is unusual); flowers more distant and 

 the calyces golden pubescent, not hoary as in A. proxima 

 and A. doratoxylon; rachis glaucous, not resinous. Pods 

 larger, flatter and more woody. 



A. SPAUSIFLORA n. Sp.
